I figured this wouldn't be too difficult to do, but I can't seem to figure out how to do it. Is there a way to easily access the current item from a ListView data source? For instance, you can easily evaluate the current item's properties using Eval("propertyName"), but is there a way to access the object itself?
And if this isn't possible, what I ultimately want to do is get the Type of the object.
I am trying to populate the ListView using LinqDataSource data source but the issue I am having is.I need to load the listview on Search button click action.
IN the page_load I kept like this:
===========================================
LinqDS.Selecting += new EventHandler<LinqDataSourceSelectEventArgs>(LinqDS_Selecting);
protected void LinqDS_Selecting(object sender, LinqDataSourceSelectEventArgs e)
{
e.Result = ObjectDS;
}
=============================================
This works fine but this happens on page load,i want this binding to happen on button click?is there a way to do this?
I have a listview set up in "flow" mode where the existing records are all on an extended page so you can scroll down to any record.
The InsertItem Template is in the first position, making it easy to insert a new record.
And one can scroll down the page to any record, click the edit button and update that record -- nice having everything on one scrollable page.
I am running into a problem with validations. I have validation controls restricting inputs for all the textboxes on the Insert Item template. They work fine. And on Item Inserted I am running a page validation:
Page.Validate()
If Not Page.IsValid Then
e.Cancel = True
End If
which works fine also.
The problem occurs when I scroll down to an existing record, and go to edit it. I have all the same validation constraints on the textboxes for the EditItemTemplate as I have on the InsertItemTemplate. But I cannot successfully do a page validation on updating the record. The code I am using on update is:
Protected Sub LVRentals_ItemUpdating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.ListViewUpdateEventArgs) Handles LVRentals.ItemUpdating
Page.Validate()
If Not Page.IsValid Then
e.Cancel = True
End If
End Sub
This results in a Cancel even if there are no validation errors on the InsertItemTemplate because the Page.Validate() seems to be causing the InsertItemTemplate to think its fields should be filled out also.
Here is the code for a typical entry of the InsertItem Template:
[code]....
All the controls in the Edit Item template are part of ValidationGroup "edit1" and those of the InsertItem Template are part of ValidationGroup "edit2"
How can I get around receiving validation errors on the InsertItem Template when I am trying to validate just the EditItemTemplate when both are present on the page?
I am using list view to display the the data but i am getting an error like An item placeholder must be specified on ListView 'ListView1'. Specify an item placeholder by setting a control's ID property to "itemPlaceholder". The item placeholder control must also specify runat="server.Even i have specified the itemplaceholder id but no use still same error.

The problem is, if i click on a linkbutton to sort, the datapager jumps always to the first page.
Is there any way to keep the current page on sorting?
I tried DataPager.SetPageProperties() on sorting event, but it doesn't work.

What I'm trying to do is: I have a listview control on my page and in my code behind, I created an SQLDataSource object which I defined its Select, Delete, Update and Insert Command strings. I then binded that datasource to my listview. When I load the page, it's obvious the select command works. however, when I perform the insert, the ItemInserted event triggers, but the itemInserted doesn't trigger and there is nothing inserted in my database.I'm not sure what to do here. I also hard coded the insert values in my insert command. So it's not depending on the form values.
